Hi,

I am new to this xml specifically saying Atom syndication, and
getting confusion with the URL used in the namespace. What it
signifies?

I tried copying the URL into address bar, its giving page not
found.

I am using the xml content like below for posting a photo to picasa
web album.

<entry xmlns="http://www.w3.org/2005/Atom">
<title>example.jpg</title>
<category scheme="http://schemas.google.com/g/
2005#kind" term="http://schemas.google.com/photos/2007#photo" />
</entry>

i tried changing 2005 from "http://www.w3.org/2005/Atom" to 2004, it
gave the bad request and error was "Invalid kind on entry".

Please let me know ASAP.

Regards
Vishwanath

Hi,

It signifies nothing. It's just a convention to name namespaces so
their names are unique.

Thanks,
Sergey

When I load <URL:http://www.w3.org/2005/Atom> into a browser I get a
page explaining
"Atom Syndication Format namespace

The namespace name http://www.w3.org/2005/Atom is intended for use as
per The Atom Syndication Format, a December 2005 Proposed Standard
developed by the IETF atompub Working Group."

so I don't understand why you say you get a "page not found".

But generally a URL used as a namespace name does not need to point to a
resource, it is just a unique name to identify element and/or attribute
names.

The Atom 1.0 syndication format specification is here:
<URL:http://tools.ietf.org/html/rfc4287>, it defines that the namespace
to be used is http://www.w3.org/2005/Atom so you should use that if you
want to build an Atom feed.
I am not sure why you want to use a different year in the name, a feed
reader will not understand names in the namespace
http://www.w3.org/2004/Atom.
